Red Devil 0645 Concrete Repair Patch, Cement Crack Filler, 5.5 Oz Squeeze Tube, Pre-Mixed, Pack of 1, Gray, Made in USA

Exactly as described. Nice and thick consistency. Doesn't "run" like other brands

I recently used this concrete patch to fix some cracks and holes in my driveway, and I’m very impressed with the results. The product was easy to apply, and the instructions were clear, making the whole process quick and straightforward. I simply mixed it with water, applied it to the damaged areas, and smoothed it out with a trowel. Once dried, the patched areas looked seamless with the rest of the concrete. The texture matched my existing surface well, and it even withstood some light foot traffic within a day or two of application. What I really appreciated was how durable the patch is—it’s held up well even through rain and temperature fluctuations, without showing signs of cracking or peeling. The concrete patch has also helped improve the overall look of my driveway. It filled in the gaps perfectly and made the surface look a lot cleaner and more uniform. It’s been a great solution for minor concrete repairs and is something I’d definitely use again for future touch-ups. Overall, I highly recommend this concrete patch for anyone dealing with cracks or holes in concrete. It’s an affordable, easy-to-use solution that delivers long-lasting results.

the product seems to work perfectly for the job, the only complaint that i have…the tube sent to me did not come with a cap. hopefully i will be able to plug the hole with something to keep the unused product from leaking or becoming hard.

This sounded too good to be true, but it's actually easy to use, and does a nice job filling little cracks and holes. I'm a renter, and have found that if I complain about little problems I might get an increase in my monthly bill. But, I was afraid bugs would make winter homes in the cracks around my door way. This isn't an elegant fix by any means (probably could be if someone wanted to take a lot more time), but it fills in openings in just a second or two, and I found it very easy to use.

The Red Devil 0645 Concrete Repair Patch is one of the most practical, no‑nonsense crack fillers you can keep on hand for fast structural touch‑ups. The pre‑mixed formula is the real advantage here—no measuring, no dust, no mixing ratios to get wrong. You squeeze it out, tool it into place, and it immediately behaves like a proper cementitious filler rather than a thin caulk. It adheres well to concrete, masonry, mortar, and even works for filling small holes in stucco, making it a versatile repair option for both interior and exterior surfaces. Once cured, it dries to a hard, sandable finish that blends cleanly with surrounding material. For hairline cracks, it flows smoothly enough to fill without shrinking; for wider gaps, it layers without slumping. The 5.5‑oz tube is ideal for targeted repairs like steps, patio cracks, foundation lines, garage floor blemishes, and small stucco imperfections where a full bag of patch mix would be overkill. Cleanup is simple with water while still wet, and the cured patch accepts paint without flashing or discoloration. If you need a reliable, ready‑to‑use filler that performs like a small‑scale concrete patch without the mess of mixing, this tube delivers consistent, repeatable results.

The Red Devil 0641 Concrete Repair Patch itself is excellent — no issues with the product at all. However, Amazon’s packaging and delivery were responsible for the damaged container I received. The shipping box was far oversized — roughly six times larger than the 1 gallon bucket — and the only packing material inside was a small amount of paper that was poorly insufficient to keep the container from rolling around. A heavy bucket like this needs proper stabilization, not a few loose sheets of paper. Because of the inadequate packing, the bucket slammed around during transit and arrived cracked open, with product spilled inside the box. Thankfully, because I ordered more than I needed, I still have enough to complete my project. This was not a product defect — it was a packaging failure. The box also had no “Fragile” or “Handle with Care” markings, which would have alerted the delivery driver to treat it appropriately. Amazon needs to address this immediately. Heavy, breakable containers should never be shipped in oversized boxes with minimal padding. This is a preventable issue that affects customer satisfaction, creates unnecessary waste, and increases the risk of claims. Great product — but Amazon must improve packaging standards for items like this.

Item as described!

This fills holes perfectly but you do need to lightly sand for smoothness

very good product, shame its not available in a sandy colour, as the grey stands out when dry , doesn't blend in with brick work .

Works great solid as a rock

I had an old concrete planter which is maybe 3 feet tall. Over the years it had cracked, and sections fell out near the base. I was about to discard it, but thought I'd try a tube of this stuff. I applied it with my hands (using gloves) and it almost immediately dried enough to hold the broken pieces back in place. I ran it along the chips and cracks and worked it in. The next day, it was fully dry and I touched up with additional paste. I know it has to cure for a while, but after an overnight drying the planter seems pretty sturdy, and I'm so pleased I was able to fix it - not sure if the planter will survive past this season, but at least I got another year out of it, maybe more. After using this paste (I bought the tube not the tub) I replaced the top and it did NOT dry out or clog the nozzle, I was easily able to squeeze more out.

I ended up dumping all the tube cement into a container because it was hard to not have the tip drip out cement everytime i squeezed.
